针对实验室内难以构造的高海情PM谱海面,采用电磁缩比测量的方法研究其电磁散射特性,首先定量分析了以淡水替代海水造成不满足物理相似性要求而引入的误差,然后讨论了缩比PM谱海面满足几何相似性条件的要求,和对粗糙海面进行缩比模拟测量的途径,根据粗糙海面缩比模拟理论与条件,在实验室内成功模拟构造满足缩比测量理论的粗糙海面。

Scaled Pierson-Moskowitz（PM） sea surface is produced to simulate high sea states that wave pool couldn＇t provide,and scaled sea surface electromagnetic scattering measurement could be carried out.The error of RCS introduced by fresh water instead of sea water is analyzed quantificationally.The geometrical similarity that required scaled PM sea surface is discussed.And the approach of scaled simulation measurement to rough sea surface is also discussed.According to the scaled simulation theory and condition of rough sea surface.A one-dimensional scaled Pierson-Moskowitz surface is produced successfully.
